Genomic stress in diseases stemming from defects in the second brain

Neurogastroenterology &Motility, EarlyView.
The enteric nervous system, a.k.a., second brain, is subject to a range of genotoxic exposures that include intrinsic oxidative stress and extrinsic agents associated with ingested foods, inflammation, and dysbiosis. Resulting DNA damage, if left unrepaired, can induce cell dysfunction or death, resulting in gut abnormalities and enteric neuropathy ...

Characterization of Oral Melanocytic Nevi in Sun‐Exposed and Sun‐Protected Regions

Oral Diseases, EarlyView.
ABSTRACT Objective Oral melanocytic nevi (OMN) are histologically similar to skin nevi; however, they are much rarer and not always related to sun exposure. This study aimed to characterize the histopathological, immunohistochemical, and molecular features of OMN in sun‐exposed (vermilion lip) and sun‐protected (intraoral) regions.

A skin explant model for studying UV‐induced DNA damage and repair

Photochemistry and Photobiology, EarlyView.
The study describes an ex vivo skin model that preserves the natural physiology of the skin while addressing ethical concerns related to animal research. We demonstrate this model maintains key characteristics and physiological responses of in vivo skin during short incubation periods. Moreover, this model requires fewer mice than in vivo testing, thus
